NEW QUESTION # 19
What is the correct syntax to define and call a function in Database?
- A.
- B.
- C.
- D.
Answer: B
Explanation:
Keyword to ad function in Dataweave transformation is fun. Hence option 2 and 4 are invalid. Also parameters needs to be passed exactly in same order as defined in function definition. Hence correct answer is' fun addKV( object: Object, key: String, value: Any) = object ++ {(key):(value)}
---
addKV ( {"hello': "world"}, "hola", "mundo" )
MuleSoft Documentation Reference : https://docs.mulesoft.com/mule-runtime/4.3/dataweave-functions DataWeave Function Definition Syntax To define a function in DataWeave use the following syntax:
fun myFunction(param1, param2, ...) = <code to execute>
The fun keyword starts the definition of a function.
myFunction is the name you define for the function.
Function names must be valid identifiers.
(param1, param2, ... , paramn) represents the parameters that your function accepts.
You can specify from zero to any number of parameters, separated by commas (,) and enclosed in parentheses.
The = sign marks the beginning of the code block to execute when the function is called.
<code to execute> represents the actual code that you define for your function.

NEW QUESTION # 32
Refer to the exhibits.
The Batch Job scope contains two Batch Steps scopes with different accept expression.
The input payload is passed to the Batch Job scope.
After the entire payload is processed by the batch job scope , what messages have been logged by the Logger component?
- A. 1.{amount=140}2.{amount=102}3.{step2amount=100}
- B. 1.{amount=140}2.{amount=102}3.{step2amount=100}4.{step2amount=40}
- C. 1.{amount=140}2.{amount=102}3.{step2amount=100}4.{step2amount=140}
- D. 1.{amount=140}2.{amount=102}3.{step2amount=100}4.{step2amount=140}5.{step2amount=102}
Answer: D
Explanation:
This question validates you knowledge on Batch Processing. Before we analyze the question , lets revise a bit about batchfilters.
Batch Filters
You can apply one or more filters as attributes to any number of batch steps.Imagine a batch job whose first batch step checks if a Salesforce contact exists for a record, and a second batch step that updates each existing Salesforce contact with new information. You can apply a filter to the second batch step to ensure it only processes records that didn't fail during the first batch step.By having batch steps accept only some records for processing, you streamline the batch job sothe Mule runtime engine can focus only on the relevant data for a particular batch step.
A batch step uses two attributes to filter records:
acceptExpression
acceptPolicy
Each batch step can accept one acceptExpression and one acceptPolicy attributes to filter records.
Use the acceptExpression attribute to process only records that evaluate to true; if the record evaluates to false, the batch step skips the record and sends it to the next one. In other words, the records with an accept expression that resolves to false are the ones that Mule filters out.
The example below filters out all records where the age is less than 21; the batch step does not process those records.
* <batch:jobjobName="batchJob">
* <batch:process-records>
* <batch:stepname="adultsOnlyStep"acceptExpression="#[payload.age >21]">
* ...
* </batch:step>
* </batch:process-records>
* </batch:job>
Mule Ref Doc : Refining Batch StepsProcessing | MuleSoft Documentation
As we are clear with above concepts , now lets understand this solution step by step.
1) Batch Step (Less than 50)
Accept expression for this batch step is less than 50. Hence elements which will go in this batch step are amount value 40 and 2. Hence output of logger in first batch step is
{amount=140}
{amount=102}
2) Batch Step (Greater than 20)
Accept condition for this batch step is greater than 20. Note that input amount values for this batch step are
100 , 140 and102 (last two values have been updated in batch step less than 50) As all values satisfy this condition out put of second logger is
{step2amount=100}
{step2amount=140}
{step2amount=102}
Hence correct answer to this question is
* {amount=140}
* {amount=102}
* {step2amount=100}
* {step2amount=140}
* {step2amount=102}
2) Batch Step (Greater than 20)
Accept condition for this batch step is greater than 20. Note that input amount values for this batch step are
100 , 140 and 102 (last two values have been updated inbatch step less than 50) As all values satisfy this condition out put of second logger is
{step2amount=100}
{step2amount=140}
{step2amount=102}
Hence correct answer to this question is
{amount=140}
{amount=102}
{step2amount=100}
{step2amount=140}
{step2amount=102}

NEW QUESTION # 36
What is the difference between a subflow and a sync flow?
- A. Subflow is synchronous and sync flow is asynchronous
- B. Sync flow has no error handlingof its own and subflow does
- C. No difference
- D. Subflow has no error handling of its own and sync flow does
Answer: D
Explanation:
Correct answer is Subflow has no error handling implementation where as sync flow has.
Subflow
A subflow processes messages synchronously (relative to the flowthat triggered its execution) and always inherits both the processing strategy and exception strategy employed by the triggering flow. While a subflow is running, processing on the triggering flow pauses, then resumes only after the subflow completes its processing and hands the message back to the triggering flow.
Synchronous Flow
A synchronous flow, like a subflow, processes messages synchronously (relative to the flow that triggered its execution). While a synchronous flow is running, processing on the triggering flow pauses, then resumes only after the synchronous flow completes its processing and hands the message back to the triggering flow.
However, unlike a subflow, this type of flow does not inherit processing or exception strategies from the triggering flow.
This type of flow processes messages along a single thread, which is ideally suited to transactional processing
NEW QUESTION # 37
Refer to the exhibits. In the choice router, the When expression for the domestic shipping route is set to "#[payload= "FR"]".
What is the output of logger after the execution of choice router is completed?
- A. "US"
- B. "Domestic"
- C. "International"
- D. A dataweave syntax error
Answer: D
Explanation:
To compare, DataWeave syntax is #[payload == "FR"].
In this case only one = is used so it will give syntax error.
Hence the correct answer is A dataweave syntax error
